Good option for the price if you just want bulbs you can turn on/off with smart devices. Colors aren't great when compared to higher end bulbs but that is to be expected.

works well with Google automations for custom colour settings

great for the price, connected with no issues. works well with Google home automations

very good, tough I like better to have a remote control instead of an app for my phone

Great value for money product! Sometimes it doesnt exactly sync with alexa but for the price its a good deal. You need to first install the app for the lights (s smart) and then link with alexa.

Works well enough with the S+ Smart app. Have not tried with others. Color range is quite limited and it doesn't get as bright as I would like but it does what it's intended to do.
